Step-by-step explanation:
If you don't usually have several events to get up on a ladder, you may not know that it can be risky if your ladder isn't angled accurately for the length you want to climb. When setting your ladder, retain the four-to-one rule: for every four feet of length you have to rise, relocate the bottom one foot apart from the wall.
